I wouldn't spin just for this, but if you spin for some other reason
you could move the above "dev_err" onto one line now.  Sorry: I should
have noticed that / done that on my patch...

Idea for a future patch: now that I look at what's left of this
function you're basically re-implementing clk_bulk_prepare_enable()
and clk_bulk_disable_unprepare() now.  I bet your code would be
cleaner / nicer by switching to that.

...possibly you might need to improve the clk_bulk_get() API to allow
for some clock to be optional, but that would be a pretty easy patch
to post up.

In any case I think it's better to do the clk_bulk switch in a future
/ separate patch, so:
